DETACHABLE SLEIGH-RUNNER.

Specification of Letters Patent.

Patented May 5, 1908.

Application filed December 12', 1907. Serial No. 406,137.

To all whom it may concern:

Be it known that I, BURDEN WHITE, a citizen of the United States, residing at Conde, in the county of Spink andState of South Dakota, have invented certain new and useful Improvements in Detachable Sleigh- Runners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in sled runners, each of which has a knee so constructed and braced as to reduce to a minimum a sidewise strain on the axle spindle when the runners strike an obstruction or drop into a rut or depression in the road, and said knee is furthermore connected to the axle spindle to have a free turning or oscillating movement on said spindle for the purpose of yielding automatically to any obstruction it may encounter.

The object of the invention is to facilitate the substitution of sleigh runners for the wheels of vehicle bodies of all descriptions and to so brace the knees of said runners that all straining of the axles in turning is obviated.

In the accompanying drawings: Figure 1 represents a side elevation of this improved runner; Fig. 2 represents a top plan view thereof; Fig. 3 represents a cross-sectional view taken on line 33 of Fig. 1.

In the embodiment illustrated, a runner 1 is shown preferably composed of wood, metal shod, and of any desired shape and dimensions.

A knee 2 which connects the runner 1 to the axle 3 of any vehicle which it is desired to mount on runners, is of forked or bifurcated construction, in which the legs 4 and 5 diverge from a point below the axle spindle, and the free ends thereof are provided with apertured feet 6 and 7 for attachment to the runner by means of suitable bolts. The upper end of this knee 2 is provided with clamping jaws 8 and 9, which extend laterally at one side beyond the legs 4 and 5 to form an elongated bearing for the spindle of the axle. These jaws are secured together by bolts, as 10, and

are adjustable to fit spindles of difierent sizes. Two brace rods 11 and 12 are secured at one end to the outer end of the lateral extension of the jaws, and at their other ends to the outer face of the runner 1 adjacent the feet of the knee, whereby said. runner is braced and prevented from spreading or being pushed inward.

A brace rod 13 is secured at one end to the front end of the runner 1 and detachably secured t0 the outer end of the spindle by a loop 14, which fits over said spindle end outside the clamp or bearing of the knee and is held in place by the bur or nut 15.

To provide for the use of a runner having a certain length clamp or bearing with spindles varying in length and prevent lateral or sidewise sliding movement of the clamp on said spindle, a sleeve 16 is provided having parallel spaced arms 17 and 18 extending from one end thereof, said arms having registering longitudinally extending slots as 19 through which a securing bolt 20 passes and through apertures in the clamping spindle bearing. lVhen it is desired to lengthen the bearing, the bolt 20 is loosened, the sleeve moved outward the required distance, and.

the bolt again tightened. To shorten the bearing the sleeve is slipped inward, after loosening the bolt, or it may be entirely removed.

I claim as my invention:

1. A detachable sleigh runner having a knee provided with a spindle bearing, a sleeve having spaced parallel arms extending from one end thereof, and means for connecting said arms with said spindle bearing.

2. A detachable sleigh runner having a knee provided with a spindle bearing, a sleeve having parallel spaced slotted arms extending from one end thereof and means for connecting said arms with said spindle bearing.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

BURDEN WHITE. Witnesses:
